  • Publication number: 20030178426
    Abstract: A drink-thru lid for a drinking cup including an annular mounting portion for sealingly engaging the drinking cup, wherein the annular mounting portion includes a downwardly extending annular skirt. The lid further includes a tear-back section extending from the annular skirt to a hinge portion located in a medial portion of the lid. The tear-back section includes a raised protrusion extending outwardly from an upper surface of the lid. A recess is further formed in a medial portion of the lid on the opposite side of the hinge portion from the raised protrusion, wherein the tear-back section may be torn away from the lid on its sides and pivoted about the hinge portion until the raised protrusion is received within the recess for holding said pivotal flap open. The raised protrusion and the recess are shaped such that the raised protrusion is frictionally engaged by the end walls of the recess.

  • Patent number: 5791509
    Abstract: A thin walled lid formed of a thermoplastic material having a generally circular center portion and an outer rim portion which fits over the cup bead and includes an integral peripheral skirt which makes up the outer side wall of the lid is disclosed. Located between the rim portion and the center portion is a recess or annular trough with an inner wall and an outer wall. The outer wall is separated into two shelves and three vertical sections. The lower shelf serves as a receiver ring upon which the lid above rests. The short vertical section located above the receiver ring effectively prevents any lateral movement of the lid above, while the lowest wall section forms the stacking ring and generally has a negative slope toward the lid skirt. Spaced periodically around the circumference of the stacking ring are positive draft flutes which have a positive slope away from the skirt and toward the center of the lid. The recess has a generally flat bottom which connects the stacking ring to the inner wall.

  • Patent number: 5784801
    Abstract: A paper drying apparatus including a first rotatable drum, wherein the first rotatable drum has an inner perimeter and an outer perimeter and a second rotatable drum having an inner perimeter and an outer perimeter. A fabric sheet for carrying a paper web is provided, wherein the fabric sheet passes around the outer perimeter of the first rotatable drum and proceeds to next pass around the outer perimeter of the second rotatable drum. As the fabric sheet conveys the paper web around the first rotatable drum, a drying air is applied to the paper web in a direction from the inner perimeter of the first rotatable drum toward the outer perimeter of the first rotatable drum, further passing through the paper web. As the fabric sheet and paper web proceed around the second rotatable drum, a drying air is applied to the paper web in a direction from the outer perimeter of the second rotatable drum toward the inner perimeter of the second rotatable drum, further passing through the paper web in a similar direction.

  • Patent number: 5755654
    Abstract: A method and apparatus for pinch perforating multi-ply web material to increase the perforation ply bond and/or perforation ply bond retention by pinching the multiple plies of web material together and then perforating the material using an anvil and perforator blade design provided on a perforating apparatus. Specifically, the apparatus comprises a roll mounted contoured perforator blade which cooperates with a beveled anvil to produce perforation ply bonds perpendicular to the length of the multiple plies of web material. The desired anvil/perforator blade interface angle between 0.degree. and 20.degree. is provided by beveling the anvil. A 15.degree. beveled anvil is preferred to provide a 5.degree. anvil/perforator blade interface angle. By pinching and bonding the leading edges and other predetermined points of the multi-ply tissue paper together before cutting, the likelihood of ply separation, missing plies and ply mismatch is greatly reduced.

  • Patent number: 5729914
    Abstract: Containers and a method for forming such containers having larger brims with reduced brim curl defects is disclosed including providing a plurality of container blanks for forming containers, forming a plurality of container shells from the plurality of blanks, accumulating the plurality of container shells at an accumulation station, subjecting at least an upper periphery of the shells to a humid atmosphere to precondition the shells with the atmosphere preferably including steam, successively removing the shells from the accumulator and subsequently forming a brim curl about an upper periphery of the shell with the shells being subject to the humid atmosphere for a predetermined time period sufficient to form defect-free brim curls by extending the forming strain limits of the paperboard material. This method being carried out by using an accumulator for accumulating the container shells for further processing.

  • Patent number: 5727458
    Abstract: An embossing apparatus and method which provides a better embossed appearance and eliminates undesired roughness on the backside of the web material. Two plies are multilevel embossed between rigid engraved rolls and backup rolls, which may be either engraved or smooth. One rigid roll has embossing elements of varying heights and perforation elements, which run in a side-by-side relationship with the corresponding perforation elements on the opposing rigid roll in a nip region of the apparatus. The multiple plies are perforation bonded between the perforation elements, which are preferably the two highest elements, thus reinforcing the other multi-level embossed pattern formed in between the perforation bonds. The embossed patterns impart a quilt-like contoured appearance to the finished product.

  • Patent number: 5704566
    Abstract: A roll of paper toweling is dispensed from the opening of a dispenser due to a manual pulling force applied to the toweling. The toweling is separated into a plurality of toweling segments by a plurality of spaced tear lines, the tear lines being straight, parallel to each other, and extending orthogonally relative to the side edges of the paper toweling. The perforated tear lines are formed of a plurality of spaced, elongated, axially aligned slits separated by frangible toweling portions extending between the slits. The frangible toweling portions are narrower near the side edges of the toweling than in the middle thereof and the distances between the centers of the toweling portions are substantially the same along the length of the perforated tear line.

  • Patent number: 5695607
    Abstract: A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particularly, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the funish sources being combined, and further, optionally adding the softener to the nascent web.
